Ablation of Hepatic Tumors through the Use of a Novel Magnetic Nanocomposite Probe: Magnetic Characterization and Finite Element Method Analysis
(Journal of Nanotechnology, 2019-03) Konku, Y.; Kutor, J.; Yaya, A.; Kan-Dapaah, K.
The authors recently proposed a novel system for thermoablation—based on nanoheating—that can potentially overcome limitations associated with previously reported techniques. The aim of this study was to evaluate the therapeutic performance of the system in the ablation of hepatic tissue, the most frequently ablated. A model nanocomposite system, maghemite nanoparticle-filled polydimethylsiloxane, was prepared, and its magnetic properties were studied as a function of nanoparticle concentration. On the basis of measured magnetic properties, a 3D finite element method (FEM) model was used to explore the development of temperature and thermal damage in nonperfused and fully perfused tissue using alternating magnetic field (AMF) parameters that are acceptable for human use. The FEM model was tested for its validity using an analytical model. The saturation magnetization increased to about 9% of the value of pure maghemite nanoparticles over the range of volume fraction (vol. %) between 1 and 5%. Lesion sizes were shown to be greatly affected by tissue perfusion and time. FEM predictions showed good agreement with results obtained with an analytical model to within 7%. Probes fabricated with magnetic nanocomposite can potentially be used to achieve reasonable lesion sizes in hepatic tissues using human-safe AMF parameters.
Activated cashew carbon-manganese oxide based electrodes for supercapacitor applications
(Scientific African, 2023) Boamah, R.; Agyei-Tuffour, B.; Dodoo-Arhin, D.; Nyankson, E.; Brobbey, K.J.; et al.
The current global energy challenge which affects most developing countries in particular, is of major source of concern today. The availability of less expensive techniques of storing excess generated energy is critical to the success of the renewable energy roadmaps implementation. In this study, hydrothermal and chemical leaching methods have been used to synthesize MnO2 nanoparticles using KMnO4 and MnSO4 as precursors at 140 °C and from natural local manganese ore. Activated Carbon (ACF) have also been produced from agricultural Cashew biomass waste, through a physical carbonization and KOH activation process using temperatures of 700 °C – 900 °C for periods between 1 and 2 h. The as-prepared materials have been characterized via XRD, Raman, FTIR, SEM. Electrochemical performance measurements (CV, EIS and GCD) were carried out on the prepared electrodes. The specific capacitance values obtained were in the range of 2.8 F/g - 6.5 F/g at different scan rates of 20 mV -50 mV respectively in a potential range of -0.4 to +0.4 V and -0.4 to +0.6 V for the various types of electrodes
Adsorbents for water decontamination: A recycling alternative for fiber precursors and textile fiber wastes
(Science of the Total Environment, 2024) Bediako, J.K.; Apalangya, V.; Hodgson, I.O.A.; Anugwom, I.; Repo, E.
The exponential growth in textile fiber production and commensurate release of textile waste-based effluents into the environment has significant impacts on human wellbeing and the long-term planetary health. To abate these negative impacts and promote resource circularity, efforts are being made to recycle these waste materials via conversion into adsorbents for water decontamination. This review critically examines plant- and regenerated cellulose-based fibers for removing water pollutants such as heavy metals, dyes, pharmaceutical and petro chemical wastes. The review reveals that chemical modification reactions such as grafting, sulfonation, car boxymethylation, amination, amidoximation, xanthation, carbon activation, and surface coating are normally employed, and the adsorption mechanisms often involve Van der Waals attraction, electrostatic interaction, complexation, chelation, ion exchange, and precipitation. Furthermore, the adsorption processes and thus the adsorption mechanisms are influenced by factors such as surface properties of adsorbents, pollutant characteristics including composition, porosity/pore size distribution, specific surface area, hydrophobicity/ hydrophobicity, and molecular interactions. Besides, feasibility of the approaches in terms of handling and reuse, environmental fate, and economic impact was evaluated, in addition to the performances of the adsorbents, the prospects, and challenges. As current cost analysis is non-exhaustive, it is recommended that researchers focus on extensive cost analysis to fully appreciate the true cost effectiveness of employing these waste materials. In addition, more attention must be paid to potential chemical leaching, post-adsorption handling, and disposal. Based on the review, fiber precursors and textile fiber wastes are viable alternative adsorbents for sustainable water treatment and environmental management, and government entities must leverage on these locally accessible materials to promote recyclability and circularity.
Advanced treatment of food processing effluent by indigenous microalgae-bacteria consortia: Population dynamics and enhanced nitrogen uptake
(Algal Research, 2023) Amadu, A.A.; Abbew, A-W.; Qiu, S.; Addico, G.N.D.; Hodgson, I.; Hodgson, I.; Duodu, S.; Appiah, S.A.; Ge, S.
The potential of indigenous microalgae-bacteria consortia (IMBC) to recover nutrients from food processing effluents (FPE) supports the basis for advanced effluent polishing and value-added biomass generation. In this study, the effluent polishing potential of an FPE-borne IMBC treating FPE and synthetic wastewater (SWW) was investigated regarding nutrient, coliform bacteria, and chemical oxygen demand (COD) removal as well as the IMBC species evolution, and pigment production. Species evolution and diversity of the IMBC in FPE and SWW were influenced by nitrogen levels (3.83 mg/L and 32.61 mg/L NH4 +, respectively). More blue-green microalgae were observed in SWW (0.96 mg/L phycocyanin) whilst diatoms dominated in FPE (0.05 mg/L phycocyanin). Total coliform bacteria removal influenced COD reduction and this had a significant effect on dissolved oxygen production. The study offers new insights into the feasibility of using IMBC biofilm for advanced FPE polishing and nutrient recovery (0.98 mg/L NH4 +, 0.85 mg/L PO4 3− , 0.84 mg/L COD, 3.2 g/L protein, and 2.8 g/L carbo hydrates), demonstrating that it is possible to use IMBC biofilm for post-treatment of FPE, removing the residual N and P to prevent eutrophication.
Advancements in Crude Oil Spill Remediation Research after the Deepwater Horizon Oil Spill
(Springer International Publishing, 2016) Nyankson, E.; Rodene, D.; Gupta, R.B.
An estimated 4.9 million barrels of crude oil and natural gases was released into the Gulf of Mexico during the Deepwater Horizon oil spill of 2010. The Deepwater Horizon oil spill affected the aquatic species in the Gulf of Mexico, vegetation, and the human population along the coast. To reduce the effect of the spilled oil on the environment, different remediation strategies such as chemical dispersant, and mechanical booms and skimmers were utilized. Over 2.1 million gallons of dispersants was applied to minimize the impact of the spilled oil. However, environmental and human toxicity issues arose due to the perceived toxicity of the dispersant formulations applied. After the Deepwater Horizon oil spill, various studies have been conducted to find alternative and environmentally benign oil spill response strategies. The focus of this manuscript is to demonstrate an objective and an overall picture of current research work on oil spill response methods with emphasis on dispersant and oil sorbent applications. Current trends in oil spill sorbent and dispersant formulation research are presented. Furthermore, strategies to formulate environmentally benign dispersants, as well as the possible use of photoremediation, are highlighted. © 2015 Springer International Publishing Switzerland.
Ag2CO3-halloysite nanotubes composite with enhanced removal efficiency for water soluble dyes
(Heliyon, 2019-06-13) Nyankson, E.; Agyei-Tuffour, B.; Annan, E.; Yaya, A.; Mensah, B.; Onwona-Agyeman, B.; Amedalor, R.; Kwaku-Frimpong, B.
The release of water soluble dyes into the environment is an utmost concern in many countries. This paper presents the effects of Ag2CO3-halloysite composites on the efficient removal of water soluble dyes. In this study, NaHCO3 solution was added dropwisely to halloysite nanotubes (HNTs) dispersed in aqueous AgNO3 to form Ag2CO3-HNTs composite. The synthesized Ag2CO3-HNTs composite was characterized with Diffused Reflectance Spectroscopy (DRS), X-ray Diffraction (XRD), Thermogravimetric analysis (TGA), Scanning Electron Microscopy- Energy Dispersive Spectroscopy (SEM-EDX) and Fourier Transform Infra-Red (FT-IR) spectroscopy. The photocatalytic activity and the adsorption capacity of Ag2CO3-HNTs on methylene blue and rhodamine b dyes were dependent on pH and the amount of HNTs used in the synthesis. The photodegradation efficiency of Ag2CO3 was lower when compared with that of the composite material. This observation is due to the reduction in the electron-hole recombination with the HNTs acting as electron trapping site and the enhanced aqueous dispersity of Ag2CO3-HNTs. The enhanced adsorption of water soluble dyes by the Ag2CO3-HNTs resulted from the electrostatic attraction of cationic dyes to the surface of the HNTs (negatively charged). The Ag2CO3-HNTs therefore removed dye pollutants through a combination of photocatalytic and adsorption processes. The results obtained during the study confirmed the potential application of Ag2CO3-HNTs composite in water treatment technologies.
Agricultural mechanization strategy and Japan Ghana Co-operation
(AMA, Agricultural Mechanization in Asia, Africa and Latin America, 2013-09) Richard, J.B.; Selorm, Y.D.
Experts discuss how Japan and Ghana are cooperating with each other to mechanize agricultural activities in Ghana. Agricultural mechanization entails the provision of mechanical power for undertaking the various agricultural productions. One of the most important aspects of agricultural mechanization is the level of expertise of the personnel available to aid in effective mechanization. Japan is helping the country in modernizing its universities, institutes, and establishing government and private centers to achieve these objectives. An example of government and private sector intervention in Ghana is the Agricultural Mechanization Centers (AMSEC). These centers provide specialized services to the farmers. There needs to be collaboration between the Ghanaian and Japanese Engineers along with the researchers so that there will be constant evaluation and improvement in the existing systems.
AlF3 reactive Al2O3 foam filter for the removal of dissolved impurities from molten aluminum: Preliminary results
(Elsevier, 2011) Damoah, L.N.W.; Zhang, L.
Filters coated with AlF3 can be used to filter molten aluminum to simultaneously remove nonmetallic inclusions and dissolved alkali and alkaline earth metal impurities. Coating experiments were carried out in which anhydrous HF gas was generated from reactions involving NaF or CaF2 and concentrated H2SO4, and used in a reaction with Al2O3 ceramic foam filter to produce a layer of AlF 3 coating on the surface of the Al2O3 filter. Samples from these experiments were studied by X-ray diffraction, scanning electron microscopy and electron probe microanalysis. Preliminary results of the coating experiments showed that it is possible to coat Al2O 3 filters with AlF3 by this method. Increasing the pressure of HF gas increased the yield of AlF3 in the filter. Theoretical evaluation of the removal efficiency of dissolve impurity elements showed that dissolved calcium can be removed up to 99.8% within 30 s of contact time between the filter material and the molten aluminum.
Analysis of the life-cycle costs and environmental impacts of cooking fuels used in Ghana
(Applied Energy, 2012-10) Afrane, G.; Ntiamoah, A.
This study evaluated the life-cycle costs and environmental impacts of fuels used in Ghanaian households for cooking. The analysis covered all the common cooking energy sources, namely, firewood, charcoal, kerosene, liquefied petroleum gas, electricity and even biogas, whose use is not as widespread as the others. In addition to the usual costing methods, the Environmental Product Strategies approach (EPS) of Steen and co-workers, which is based on the concept of 'willingness-to-pay' for the restoration of degraded systems, is used to monetise the emissions from the cookstoves. The results indicate that firewood, one of the popular woodfuels in Ghana and other developing countries, with an annual environmental damage cost of US$ 36,497 per household, is more than one order of magnitude less desirable than charcoal, the nearest fuel on the same scale, at US$ 3120. This method of representing the results of environmental analysis is complementary to the usual gravimetric life-cycle assessment (LCA) representation, and brings home clearly to decision-makers, especially non-LCA practitioners, the significance of environmental analysis results in terms that are familiar to all. © 2012.
Annealing effects on interdiffusion in layered FA-rich perovskite solar cells
(AIP Advances, 2021) Oyewole, D.O.; Koech, R.K.; Ichwani, R.; Ahmed, R.; Tamayo, J.H.; Adeniji, S.A.; Cromwell, J.; Ulloa, E.C.; Oyewole, O.K.; Agyei-Tuffour, B.; Titova, L.V.; Burnham, N. A.; Soboyejo, W. O.
Annealing is one of the processing methods that are used for the fabrication of defect-free, photoactive perovskite films with compact grains in highly efficient and stable perovskite solar cells (PSCs). Thus, the annealing temperature is a key parameter for the control of the interdiffusion (of constituent elements) in photoactive films. In this paper, we present the results of a systematic study of the effects of annealing on the interdiffusion of constituent elements in efficient formamidinium-based PSCs. We also explore the effects of annealing-induced interdiffusion on layer microstructures, local strains, and the optoelectronic properties of perovskite films. We observe a dramatic upward diffusion of tin (Sn) and titanium (Ti) from fluorine-doped tin oxide and titanium dioxide (TiO2) to the perovskite films. We also observe a downward diffusion of lead (Pb) and iodine (I) from the perovskite films to the mesoporous layer of the electron transporting layer (ETL), after annealing at temperatures between 100 and 150 ○C. The diffused I substitutes for Ti in the ETL, which improves the optoelectronic properties of the films, for annealing temperatures between 100 and 130 ○C. The annealing-induced interdiffusion that occurs at higher temperatures (between 140 and 150 ○C) results in higher levels of interdiffusion, along with increased local strains that lead to the nucleation of pores and cracks. Finally, the implications of the results are discussed for the design of PSCs with improved photoconversion efficiencies and stability.
Application of clay ceramics and nanotechnology in water treatment: A review
(Cogent Engineering, 2018-07) Annan, E.; Agyei-Tuffour, B.; Bensah, Y.D.; Konadu, D.S.; Yaya, A.; Onwona-Agyeman, B.; Nyankson, E.
The increasing demand to provide clean water for drinking has brought to the fore the importance of seeking other materials with the ability or combined effect with other materials to purify water. Clay ceramics are known to be natural and also easily engineered porous-structured materials. Review papers on water filtration over the last decade have been on specific mechanisms or technologies. This review paper presents a single platform which provides information encapsulating all these technologies. This paper highlights water contaminants, and their various treatment technologies. The effectiveness of these technologies are evaluated via scholarly documented peer-reviewed papers. Moreover, the discussions are interspersed with the World Health Organization’s (WHO) standard for various contaminants along with the exploration of the efficiency of clay minerals as potent water filtration material. Finally, current trends in application of nanotechnology in water purification systems are also highlighted. These technologies include adsorption, microbial disinfection, and photocatalysis.
Assessing Ghana’s eHealth workforce: implications for planning and training
(Human Resources for Health, 2018-11) Ogoe, H.A.; Asamani, J.A.; Hochheiser, H.; Douglas, G.P.
Background eHealth—the proficient application of information and communication technology to support healthcare delivery—has been touted as one of the best solutions to address quality and accessibility challenges in healthcare. Although eHealth could be of more value to health systems in low- and middle-income countries (LMICs) where resources are limited, identification of a competent workforce which can develop and maintain eHealth systems is a key barrier to adoption. Very little is known about the actual or optimal states of the eHealth workforce needs of LMICs. The objective of this study was to develop a framework to characterize and assess the eHealth workforce of hospitals in LMICs. Methods To characterize and assess the sufficiency of the workforce, we designed this study in twofold. First, we developed a general framework to categorize the eHealth workforce at any LMIC setting. Second, we combined qualitative data, using semi-structured interviews and the Workload Indicator of Staffing Needs (WISN) to assess the sufficiency of the eHealth workforce in selected hospitals in a LMIC setting like Ghana. Results We surveyed 76 (60%) of the eHealth staff from three hospitals in Ghana—La General Hospital, University of Ghana Hospital, and Greater Accra Regional Hospital. We identified two main eHealth cadres, technical support/information technology (IT) and health information management (HIM). While the HIM cadre presented diversity in expertise, the IT group was dominated by training in Science (42%) and Engineering (55%), and the majority (87%) had at least a bachelor’s degree. Health information clerk (32%), health information officer (25%), help desk specialist (20%), and network administrator (11%) were the most dominant roles. Based on the WISN assessment, the eHealth workforce at all the surveyed sites was insufficient. La General and University of Ghana were operating at 10% of required IT staff capacity, while Ridge was short by 42%. Conclusions We have developed a framework to characterize and assess the eHealth workforce in LMICs. Applying it to a case study in Ghana has given us a better understanding of potential eHealth staffing needs in LMICs, while providing the quantitative basis for building the requisite human capital to drive eHealth initiatives. Educators can also use our results to explore competency gaps and refine curricula for burgeoning training programs. The findings of this study can serve as a springboard for other LMICs to assess the effects of a well-trained eHealth workforce on the return on eHealth investments.
Assessing the impact of industrial and urban wastes on the irrigation water quality of three streams in a semi-arid coastal savannah catchment in Ghana
(Journal of Food, Agriculture and Environment, 2013-02) Danso, E.O.; Abenney-Mickson, S.; Sabi, E.B.; Osae, S.K.; Akiti, T.T.
Anthropogenic disturbances have had and continue to have an impact on the aquatic ecosystem of Ghana. The purpose of the study was to investigate the impact of anthropogenic activities on the irrigation water quality of three streams in southern Ghana. In the present study, the chemical quality of three streams under different (industrial and urban) land use within the same catchment in Ghana was examined using standard methods of Environmental Protection Agency (EPA) and American Public Health Association (APHA) to evaluate the effects of human activities on irrigation water quality. Analyses showed that all the streams were neutral to slightly alkaline. Relatively high concentration of salinity (ECw) and Sodium Absorption Ratio (SAR) were found in streams in industrial and high density residential areas. In addition, the mean values of major cations (Na+, K+, Ca2+ Mg2+) and anions (SO4 2-, Cl-HCO3 -) were high in industrial and high density residential areas. Trace metal (Fe2+, Mn2+ Zn2+Cu2+, Cr3+, Pb2+, Cd2+) concentrations were generally low and did not show any trend under different types of land uses. The results showed that all the three streams were generally unsuitable for irrigation and should be used with caution.
Assessment of fluoride removal in a batch electrocoagulation process: A case study in the Mount Meru Enclave.
(Scientific African, 2021) Mureth, R.; Machunda, R.; Njau, K.N.; Dodoo-Arhin, D.
The presence of excessive amounts of fluoride than prescribed standards has been reported in various sources of domestic water supply around the slopes of Mount Meru and other parts in Tanzania. Efforts to remove the excessive fluoride have been carried out using various technologies. In this study, electrocoagulation experiments were carried out to as- sess its efficiency on fluoride removal. The fluoride concentration tested ranged from 1.37 to 48 mg/L in both synthetic and natural waters. The voltage applied in the electrocoag- ulation (EC) process ranged from 0 to 50 V while maintaining pH values of 4 to 9. The representative experimental results for the Ngarenanyuki river water with initial fluoride concentration of 29.5 mg/L accomplished a removal efficiency of 90% at an optimal elec- trolysis time of 30 min, an applied voltage of 30 V and an optimal pH of 6. The method showed efficient fluoride removal in water to allowable limits by World Health Organiza- tion (WHO) and Tanzania Bureau of Standards (TBS) (1.5 mg/L). Despite the voltage applied (30 V), the pH at neutrality remained unchanged thus making the process more efficient. At this voltage (30 V) the process has been reported previously also to have the capability of disinfecting the water and hence rendering such water safe for use.
An automated method for developing search strategies for systematic review using Natural Language Processing (NLP)
(MethodsX, 2023) Kwabena, A.E.; Wiafe, O-B.; John, B-D.; Bernard, A.; Boateng, F.A.F.
The design and implementation of systematic reviews and meta-analyses are often hampered by high financial costs, significant time commitment, and biases due to researchers’ familiarity with studies. We proposed and implemented a fast and standardized method for search term selection using Natural Language Processing (NLP) and co-occurrence networks to identify relevant search terms to reduce biases in conducting systematic reviews and meta-analyses. • The method was implemented using Python packaged dubbed Ananse, which is benchmarked on the search terms strategy for naïve search proposed by Grames et al. (2019) written in “R”. Ananse was applied to a case example towards finding search terms to implement a systematic literature review on cumulative effect studies on forest ecosystems. • The software automatically corrected and classified 100% of the duplicate articles identified by manual deduplication. Ananse was applied to the cumulative effects assessment case study, but it can serve as a general-purpose, open-source software system that can support extensive systematic reviews within a relatively short period with reduced biases. • Besides generating keywords, Ananse can act as middleware or a data converter for integrating multiple datasets into a database.
Availabilty of energy and agricultural mechanization in Ghana
(Journal of Food, Agriculture and Environment, 2008) Josiah, M.N.; Bani, R.J.; Mahama, A.A.
A variety of definitions have been postulated for food security. The bottom line, however, is the availability of food of good quality at an affordable cost to all and at all times. Many approaches have been adopted to achieve an increase in the availability of food. These include among others increased use of mechanization to expand area under cultivation. Many developing countries have adopted agricultural mechanization to modernize and speed up the process of agricultural land expansion. The available land in Ghana that is suitable for mechanization is put at 8 million hectares for which an estimated energy input of 6 × 106 kW is required. Of this amount only 3.1% is available. Analysis have shown that out of the 1.6 million hectares of land currently under mechanized cultivation the required energy input is 12 × 105 kW out of which only 15.6% is available. This shows a wide gap between the energy required and what is available to meet the objectives of agricultural mechanization.
Awaso bauxite red mud-cement based composites: Characterisation for pavement applications
(Case Studies in Construction Materials, 2017-12) Dodoo-Arhin, D.; Nuamah, R.A.; Agyei-Tuffour, B.; Obada, D.O.; Yaya, A.
This paper presents the development of Bauxite residue (red mud) based cement composite mortar blocks for applications in pavement construction. The experimental techniques considered include the structural, thermal, morphological and microscopy analysis of the raw bauxite and red mud samples calcined at 800 °C. Composite mortar blocks of different batch formulations were produced and their physicochemical properties were investigated. The results show that the compressive strength of the as-prepared composite mortar blocks increased by ∼40% compared to the type M mortar strength of ∼2500 N/mm2. The load bearing applications of the composites are discussed to influence the adoption of the calcined red mud as supplement in the production of low-cost Portland cement based composite mortar blocks for the construction industry. © 2017
Band gap engineering via edge-functionalization of graphene nanoribbons
(Journal of Physical Chemistry C, 2013-12) Wagner, P.; Ewels, C.P.; Adjizian, J.-J.; Magaud, L.; Pochet, P.; Roche, S.; Lopez-Bezanilla, A.; Ivanovskaya, V.V.; Yaya, A.; Rayson, M.; Briddon, P.; Humbert, B.
Density functional calculations are used to perform a systematic study of the effect of edge-functionalization on the structure and electronic properties of graphene nanoribbons (GNRs). -H, -F, -Cl, -Br, -S, -SH, and -OH edge-functionalization of armchair, zigzag, and reconstructed Klein-type GNRs was considered. The most energetically favorable edge structure varies depending on the choice of functional group. It is shown, for the first time, that reconstructed Klein-type GNRs are important stable configurations for several edge-functional groups. Band gaps using three different exchange-correlation functionals are calculated. The band gap for armchair GNRs can be tuned over a range of ∼1.2 eV by varying the edge-functional groups. In contrast, the band gaps of zigzag and reconstructed Klein edge GNRs are largely insensitive to the choice of edge-functional group, and ribbon width is instead the defining factor. Alternatively, the armchair GNR band gap can be controlled by varying the number of functional groups per opposing edge, altering the GNR "effective" width. Edge-functionalization design is an appropriate mechanism to tune the band gap of armchair GNRs. © 2013 American Chemical Society.
Beneficial and technological analysis for the recycling of solar grade silicon wastes
(2011) Dong, A.; Zhang, L.; Damoah, L.N.W.
In the current paper, different kinds of silicon wastes during the production of SoG-Si were summarized and the beneficial analyses, such as financial value, energy value, CO2 emissions, and efficiency and energy payback time, were briefly discussed for the recycling of SoG-Si wastes. Possible technologies to recycle and purify SoG-Si wastes were reviewed: such as filtration, sedimentation, solidification control, electromagnetic separation, plasma oxidation, centrifugation, and high temperature remelting process, et al.
Benefits of Activity-Based Interventions Among Female Adolescents Who Are Overweight and Obese
(Pediatric Physical Therapy, 2019-10-01) Bonney, E.; Ferguson, G.; Burgess, T.; Smits-Engelsman, B.
Purpose: The purpose of this study was to compare the effects of 2 activity-based motor interventions among female adolescents who are overweight and obese. Methods: This study was conducted in a low-income community of Cape Town, South Africa. The study involved 52 participants classified as overweight and obese. Participants were randomly assigned to task-oriented functional training or Wii Fit intervention. Both interventions were 45 minutes of active training once a week for 14 weeks. Outcome measures included aerobic fitness, motor coordination, and self-efficacy. Data were collected before and after the interventions. Results: Participants in both groups demonstrated significant improvement in aerobic fitness and motor coordination but not self-efficacy. However, no between-group differences were observed on any of the outcomes. Conclusions: Activity-based interventions may improve aerobic fitness and motor coordination in female adolescents who are overweight and obese and may also help prevent declines in physical fitness and coordination in this population.
